Detailed explanation-1: -The four phases of complete metamorphosis are egg, larva, pupa, and adult. Incomplete metamorphosis permits some of the insect’s exoskeleton to persist throughout its life cycle. The complete metamorphosis of the insect involves an entire moulting of its exoskeleton.

Detailed explanation-2: -4 stage life cycle (complete metamorphosis). The four stages are egg, larva, pupa and adult. During the pupa phase much of the body is destroyed and rebuilt so that the adult insect looks completely different, and may well eat different foods, from the larva.

Detailed explanation-3: -When the immature insects and the adults have different forms, the process is called complete metamorphosis, and the worm, or grub, like juvenile insects are called larvae. After the last larval instar, the insect changes into a pupa. In this stage, the insect does not feed or move around much.

Detailed explanation-4: -This set of four stages – egg, larva, pupa, and adult – makes up the process of complete metamorphosis.
